Dijkstra 算法是求解有向图中单源最短距离(Single Source Shortest Path,简称为 SSSP)的经典算法。 最短距离:对一个有权重的有向图 G=(V,E),从一个源点 s 到汇点 v 有很多路径,其中边权和最小的路径,称从 s 到 v 的最短距离。 算法基本原理,如下所示: 初始化:源点 s 到 s 自身的距离(d[s]=...
HDU-4725-The Shortest Path in Nya Graph(拆点,最短路) 题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4725 题目大意:给出n个点,这n个点分布在不同的高度上,花费C,可以跳转到相邻的两层之间的任意一个点。给出m条边,这是额外的可行道路。问从1~n的最短路是多少,没有最短路输出-1,本层之间...

As the algorithm progresses and nodes are removed from the dictionary, it calculates the shortest paths to all other nodes from the starting node. The process ends when the dictionary is empty, at which point all shortest paths from the source node to all other nodes in the graph...
1. The autowave-competition neural network (ACNN) is proposed to successfully resolve the problem of single-source shortest paths (SSSP). 将竞争机理引入网络的自动波产生与传播过程中,提出自动波竞争神经网络(ACNN)模型,并成功地应用于求解单源最短路问题,给出了基于ACNN的最短路求解算法。

We present a simple parallel algorithm for the single-source shortest path problem in planar digraphs with nonnegative real edge weights. The algorithm runs on the EREW PRAM model of parallel computation in O((n2ε+n1ε)logn) time, performing O(n1+εlogn) work for any 0<ε<1/2. The st...
